Product Structural Features 

FRP/PVC-U and FRP/PVC-C (composite pipes and fittings) are lined with chemical-grade PVC-U and PVC-C pipes and fittings, reinforced with fiberglass reinforced plastic (FRP) using an interfacial adhesive and specialized mechanical winding techniques.

Combining the excellent corrosion resistance of PVC-U and PVC-C with the high strength and temperature resistance of FRP, they overcome the shortcomings of PVC-U and PVC-C, such as poor pressure resistance at high temperatures and susceptibility to outdoor aging. This expands the application range of single PVC-U and PVC-C piping systems and FRP pipes. FRP/PVC-U and FRP/PVC-C composite pipes and fittings offer excellent impact resistance, low fluid resistance, and resistance to electrochemical corrosion. They are suitable for use in industries such as steel, metallurgy, petroleum, chemicals, fertilizers, pharmaceuticals, power generation, sewage treatment, copper foil, polysilicon, rare earth metals, graphite, new energy, energy storage, electronics and semiconductors, and chlor-alkali.
